I am running 2 python programs each talking to a different Arduino card through Pyserial. When doing this on windows 7 everything works fine and I can run both python scripts at the same time to talk to the 2 arduino cards.

Now when I try this on Mac I can only run 1 program at a time through Idle. When one script is running and I try the second it stops the first one. Each program runs fine by itself but I can’t run both programs simultaneously. I have tried this with Python Launcher but when I do I get an error message. “No module named serial”.

A) How do I get Idle to run 2 scripts simultaneously? and orb) How do I get python launcher to find Pyserial?
